[PATCH] ieee80211: Fixed a kernel oops on module unload
tree 367069f24fc38b4aa910e86ff40094d2078d8aa7 parent a33a1982012e9070736e3717231714dc9892303b author James Ketrenos <jketreno@linux.intel.com> 1124430800 -0500 committer James Ketrenos <jketreno@linux.intel.com> 1127310571 -0500 Fixed a kernel oops on module unload by adding spin lock protection to ieee80211's crypt handlers (thanks to Zhu Yi) Modified scan result logic to report WPA and RSN IEs if set (vs.being based on wpa_enabled) Added ieee80211_device as the first parameter to the crypt init() method. TKIP modified to use that structure for determining whether to countermeasures are active. Signed-off-by: James Ketrenos <jketreno@linux.intel.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
